Background: Effective disaster preparedness protects pregnant women, a disadvantaged group, and reduces potential harm.

Aim: This study was planned to determine the effects of training provided to pregnant women regarding disasters on their knowledge and disaster preparedness levels.

Methods: A total of 140 participants (70 in the experimental group and 70 in the control group) who attended the obstetrics and gynecology outpatient clinics of a state hospital in western Turkey between November 2023 and December 2024 and met the inclusion criteria were included in the study. Data were collected through face-to-face interviews using pre-test and post-test forms and standardized questionnaires.

Results: It was determined that 34.3% of the pregnant women in both the experimental and control groups were aged between 26 and 30 years. In the experimental group, 34.3% of the participants were high school graduates, whereas 34.3% of those in the control group were undergraduate graduates. The mean gestational week was 33.41 ± 7.25 in the experimental group and 20.79 ± 11.68 in the control group. Following the training intervention, disaster knowledge levels of pregnant women in the experimental group increased markedly, with no incorrect responses observed in the post-test assessment. A statistically significant difference was found between the post-test total scores of the Disaster Preparedness Scale in the experimental and control groups (t = 23.23, p < 0.001, Cohen's d = 3.93), indicating a very large effect size of the training intervention. In contrast, no statistically significant difference was found between the pre-test scores of the two groups (t = - 1.04, p = 0.30).

Conclusions: The training provided to pregnant women, a vulnerable group, emphasized the importance of pre-disaster preparedness and increased their knowledge and awareness. These findings highlight the need to integrate disaster preparedness education into routine prenatal care programs and broader clinical practice.

Introduction: Lifestyle interventions are critical for optimizing maternal and child health outcomes during pregnancy. As a mind-body exercise rooted in the principles of traditional Chinese Medicine (TCM), qigong shows promise as adaptable prenatal interventions, but the evidence is limited.

Objective: This multicenter randomized controlled trial (RCT) protocol aims to evaluate the additive effect of a qigong intervention program, compared to routine lifestyle intervention alone, on reducing the rate of caesarean section (primary outcome) and improving a range of secondary maternal and child health outcomes.

Methods: This multicenter RCT will be conducted across 11 institutions in China. A total of 1062 participants aged 18-45 years, with singleton pregnancies at 11-13^+ 6 weeks of gestation, will be enrolled and randomly allocated to two groups using a central stratified block randomization method. Participants will be randomized to either a control group receiving standard prenatal care plus evidence-based lifestyle education (encompassing nutrition, physical activity, sleep hygiene, stress management, and environmental avoidance), or an intervention group receiving all control components supplemented with supervised pregnancy-adapted qigong intervention (a modified seated Baduanjin exercise program). The primary outcome is caesarean section rate. Secondary outcomes include obstetric complications (abortion, preterm birth, gestational diabetes mellitus, gestational hypertension, postpartum hemorrhage, fetal growth restriction), neonatal indicators (birth weight, Apgar scores), maternal gestational weight gain, and mental health and sleep-related outcomes assessed through validated instruments such as Perceived Stress Scale-4 (PSS-4) for stress levels, Fear of Birth Scale (FOBS) for fear of childbirth, and Brief Pittsburgh Sleep Quality Index (B-PSQI) for sleep quality.

Conclusion: This rigorously designed multicenter RCT protocol addresses a significant gap by investigating whether integrating the traditional mind-body practice of qigong into standard prenatal lifestyle education confers additional benefits for reducing cesarean sections and enhancing broader maternal-child health metrics. The findings will provide robust evidence on the clinical value of this TCM intervention in integrative prenatal care to improve pregnancy outcomes and maternal and child well-being.

Abnormal birth weight, including macrosomia and low birth weight, constitutes a significant global health burden associated with both immediate neonatal risks and long-term metabolic complications. However, accurate prediction remains challenging due to fragmented clinical indicators and a lack of model interpretability, limitations often inherent in traditional statistical approaches that struggle with complex, high-dimensional data. This study developed interpretable machine learning models that integrate multifaceted maternal and fetal characteristics to enhance prediction accuracy and facilitate causal analysis. Key features were identified through statistical significance and correlation tests, and causal inference was conducted using G-computation. Among 14 evaluated models, XGBoost achieved optimal performance with AUC values of 0.997 for macrosomia and 0.992 for low birth weight. Feature importance analysis revealed distinct pathogenic pathways-metabolic and biometric factors were most predictive for macrosomia, whereas placental and hemodynamic factors dominated low birth weight prediction. These insights provide a robust and interpretable framework for early risk detection, supporting personalized antenatal management and improved perinatal healthcare strategies.
